Throttle Adjustment

Newbie question here... I read the manual to adjust my throttle and it states to tighten the ROLLOFF cable all the way down and after adjusting the ROLLON cable, loosen the ROLLOFF cable until you feel resistance(Throttle held closed)...

When I losen the ROLLOFF cable to engage the throttle down, I don't seem to ever feel the "resistance." I do notice that the throttle will start to automatically rollback as I loosen the ROLLOFF adjuster, but I am not sure how far I should loosen?

What do you'all think?

I'm not at home so I don't have a manual, but if your talking about adjusting the slack out of the throttle this can all be done from on top.......
